1. Florida-Friendly Landscaping™ (FFL) Irrigation System Survey Claire Lewis & Mackenzie Boyer

2. Why we developed this set of survey instruments Need quantitative data FFL Water Savings Table Survey was developed based upon this metric

3. Water savings table Objective: Develop measurable metric for impact of FFL practices adopted by residential water customers

4. Irrigation Requirements Estimation Turfgrass Annual Water Req. N FL, 33 inches/yr S FL, 43 inches/yr =3,700 gal/1,000 sq ft 1” = 623 gal/1,000 sq ft

5. Irrigation run time recommendations: EDIS Publication AE220 Average = 29.4 min event -1

6. Baseline irrigation case

9. 1. Rain sensor Savings based on plot study of 5 types of rain sensors and IFAS-recommended irrigation settings 8% reduction= 2,541 gal/ 1,000 sqft savings

10. 2. Calibrate sprinklers to ½” or ¾” EDIS Publication ENH63 recommends ½”-¾” per irrigation event 25% reduction= 7,942 gal/ 1,000 sqft savings 50% reduction= 15,884 gal/ 1,000 sqft savings

11. 3. Calibrate sprinklers to replace 60% of ET EDIS Publication AE436 indicates 60% ET replacement generally adequate 40% reduction= 12,707 gal/ 1,000 sqft savings

12. 4. Smart controllers ET controllers: 41-43% reduction Soil moisture sensors: 35-72% reduction 35% reduction= 11,118 gal/ 1,000 sqft 72% reduction= 22,872 gal/ 1,000 sqft

13. 5. Convert turfgrass to landscape bed EDIS Publication ENH860 recommends ornamental plants irrigated only as needed after establishment Microirrigation: 48% reduction in irrigation 100% reduction= 31,787 gal/1,000 sqft savings 48% reduction= 15,589 gal/1,000 sqft savings

14. 6. Rain barrels Irrigation savings for turfgrass from using of 55-gal rain barrel was simulated 6% reduction= 1,906 gal/1,000 sqft savings fyn.ifas.ufl.edu/barrels.htm

15. 7. Convert spray heads to MSMTs Multi-stream multi- trajectory nozzles typically have greater uniformity and have lower flow rates 67% reduction= 21,191 gal/1,000 sqft www.turfmagazine.com/content/TF/2013/04/A 9379_1_full.jpg

16. There are 3 survey instruments in this set The FFL Irrigation System Survey Intended to be given prior to FFL workshop FFL Knowledge gain Survey Intended to be given after FFL workshop Irrigation System Follow-up Survey Intended to be given 6-12 months after FFL workshop

17. What is Qualtrics Web-based survey system Logic based Interactive questions Data can be analyzed as it is collected Can be exported to PowerPoint, Word, Excel, or PDF lynda.com - online training library

18. How administered Online through Qualtrics Agents MG

19. Who is the survey intended for Homeowners who have an in ground irrigation system

20. What are the benefits to the agents to use Clear, consistent and measurable reporting tool SMART objective Next steps fertilizer pest management We are now going to go through the survey
